Abstract

The invention discloses an anti-active-jamming method in wind profile radar signal detection. The method comprises the following specific steps: firstly constructing a wind profile radar anti-active jamming system which comprises an intra-pulse inter-pulse modulation circuit (3), an intra-pulse inter-pulse demodulation circuit (4), an intra-pulse modulating sequence generating circuit (1), an inter-pulse modulation sequence generating circuit (2), a pulse signal source (5) and a signal processor (10); secondly, generating a modulation sequence by the intra-pulse modulating sequence generatingcircuit (1) and the inter-pulse modulation sequence generating circuit (2); thirdly, modulating an emitting signal by the intra-pulse inter-pulse modulation circuit (3); and fourthly, demodulating and pre-processing an echo signal by the intra-pulse inter-pulse demodulation circuit (4); and therefore, the wind profile radar anti-active jamming method is realized. The anti-active jamming method can effectively resist the external active jamming, improve the detection ability to a target signal and obviously enhance the detection result of the wind profile radar.

Description

technical field [0001] The invention relates to a wind profile radar signal detection method, in particular to an anti-active interference method in wind profile radar signal detection. Background technique [0002] Wind Profiling Radar (WPR) is an all-weather atmospheric remote sensing detection device that continuously detects physical quantities such as atmospheric wind field by detecting the reflection and scattering of electromagnetic waves by atmospheric turbulence. What the wind profile radar detects is the constantly moving atmospheric turbulence. It measures the atmospheric wind speed and wind direction by detecting the overall movement of the uneven structure of the atmospheric turbulence cluster. One of the devices. [0003] Wind profiler radars mainly work in VHF and UHF frequency bands, which are very close to radio, television and wireless communication frequency bands, and the electromagnetic environment is extremely harsh. Since the reflection and scatterin...
